What I don't understand tho, as you allready started to solder/desolder some parts... Why didn't you just desolder the power-plug of the RasPI or USB-Hub and make a permanent wired connection between the two boards? Same for the USB-ports ofc. Would've been even better imho and it would look neater aswell.
